    The framework of the study is a comparison of two groups of patient: one group formed of people affected by the pathological condition (cases) and the other constituted by people with the same features as the cases but free from the pathological condition to be analysed (controls). The crucial aspect of the design of a case–control study is that the cases are correctly selected, since the reliability of the study itself depends on this

    The comparison between the old techniques and the new one (LG and LP versus Direct) showed a lower incidence of complications among the animals that underwent the new direct technique (P < 0.05). This technique could be applied clinically in selected pediatric cases either of transplantation or reflux

    Transvaginal laparoscopic cholecystectomy: endoscopically assited

    The advent of NOTES on the scene has attracted attention and enthusiasm, but also caution and recommendations for animal studies that better define the surgical technique, test new dedicated instruments, overcome potential problems, and explore applicability to clinical settings [2]. Following this recommendation, a large number of animal studies have been performed during the last 3 years [3]. The experimental techniques described by Bessler et al. and by us are good examples of this strategy for the safe development of NOTES technology. However, the two techniques are two sides of the same coin: one is endoscopically based with laparoscopic assistance; the other is laparoscopically based, with endoscopic assistance. Both of the procedures are performed with conventional endoscopic and laparoscopic devices, which are not specifically designed for this type of surgery, making necessary a hybrid approach to ensure safe and reliable operation.When a multitasking flexible platform becomes available, these technical differences will be overcome and pure NOTES procedures will be accessible to the majority of endoscopic/laparoscopic surgeons. At that point, the two sides of the coin will be the sam

    The jejunal free flap is a standard technique in the reconstruction of hypopharyngeal and cervical esophageal defects. Conventional harvesting of the jejunal segment is performed with midline open laparotomy, which is associated with complications including prolonged ileus, abdominal pain, wound infection or dehiscence. Laparoscopic resection of the small intestine is a well documented surgical technique. Two different methods of laparoscopic harvest of a jejunal autografts for their cervical implantation have been already described. In both cases, low complication rate and better postoperative course have been observed in the patients treated. During the last 10 years, we have performed 43 circumferential pharyngoesophageal resection for advanced hypo-pharyngeal cancer followed by reconstruction with a free flap of jejunum. All but one the jejunal segments have been harvested with conventional open laparotomy. In the last patient of this group, laparoscopic harvest of the jejunal segment has been successfully performed. In this paper, we describe the laparoscopic technique used and we compare the postoperative course of this patient with those of the patients treated with conventional technique
